Abstract

The embodiment of the invention discloses a double-fuel integrated electronic control ejector, which comprises an ejector main body, wherein the ejector main body is provided with a first fuel inlet, a second fuel inlet, a first control cavity, a second control cavity, a fuel injection outlet, a fuel switch control valve and a fuel injection control valve; the first control cavity is communicated with the first fuel inlet and the second fuel inlet; the second control cavity is located under the first control cavity and is communicated with the first control cavity; the fuel injection outlet is communicated with the second control cavity; the fuel switch control valve is used for controlling the supply switch of a first fuel and a second fuel; and the fuel injection control valve is arranged in the second control cavity, and is used for controlling the communication or stop of the second control cavity and the fuel injection outlet. According to the embodiment of the invention, the double-fuel integrated electronic control ejector has the advantages that the structure is simple; the installation is convenient; the smooth switch between different fuels can be realized; an original vehicle ejector can be directly replaced by the double-fuel integrated electronic control ejector, and the double-fuel integrated electronic control ejector is mounted at the position of the original vehicle ejector, so that an optimal injection angle can be reached, and fuel consumption can be reduced; and in addition, no oil film sedimentation and coverage occur.

Description

Technical field: [0001] The invention relates to a dual-fuel electronic control injector, in particular to a dual-fuel integrated electronic control injector. Background technique: [0002] With the focus on vehicle economy and alternative fuel economy and environmental protection, automakers and refitting markets turn to more economical and environmentally friendly vehicles in order to improve efficiency and energy conservation and environmental protection, so the effective use of alternative fuels or dual-purpose fuels or multiple fuels use, requires a unique configuration of traditionally fueled engine components. [0003] In order to adapt to the mixed use of multiple fuels or the selective switching of use, dual-fuel or multi-fuel economical and environmentally friendly vehicles that are refitted or produced are generally based on the original vehicle, and the intake manifold is refitted with new fuel connected to the intake manifold. The injector, the original vehicle...
